JAKOB GUDMOND-HOYER, OF MORRIS, NEW YORK.

. YMIEGIHAN ISM FOB BORING HOLES IN THE EARTH.

Original application filed April 9, 1914,

T0 all wh-0m it may concern 5 Be it. known that I, JAKOB V. GUDMOND- HYER, a citizen of the Unitedv States, residingat Morris, in the county'of Otsego and State of New York, have invented certain new and useful Improvements in Mechanism for Boring Holes in the Earth, of which the following is a specification.

`The present invention relates generally to improvements in machines for yboring holes in the earth and is particularly adapted for subsoiling apparatus of the type disclosed in my copending application Serial Number 830,833, filed April 9, 1914, of which this application is a division. While the mechanism is especally adapted for boring'a hole in the earth in which to deposit the explosive charge for breaking up the soil, the apparatus is susceptible of use for other purposes, as for instance in setting `fence posts or planting trees.

In carrying out'my inventionl preferably mount the whole operating mechanism upon a motor -vehicle, the propelling means for said vehicle being employed for actuating a hole boring tool and in conjunction with the apparatus I kprovide means for automatically arresting movement of the vehicle at predetermined distances so as to enable the holes to .be at regular intervals apart.

These and such other objects as lmay hereinafter appear are attained by the 'novel construction, combinationand arrangement of parts to be hereinafter specifically described and claimed. f

Reference will now be had to the accompanying drawings forming a part of this specification, wherein l i Figure 1 is a side elevation of an apparatus constructed in accordance with my invention. Fig. 2 is a front elevation of the same. Fig. 3 isv an enlarge'ddetail view of the clutch operating mechanism for the hole boring toolr employed in the apparatus. Fig. 4 is a horizontal sectional viewon the line 4li lof Fig. 3. Fig.` 5 isa detail elevation of the vehicle brake;L 'Fig'. 6 is a similar elevation of the automatic means for lapplying the brake at predetermined points during movement of the vehicle, and Fig. 7 is a horizontal sectional view on the une v vof rig. 6.

connected through the driving chains 4' t0 the rear driving wheels 5. It will be understood that any desired design of vehicle may'readily'be used invcarrying out this apparatus, and I do not wish to be strictly confined with respect to the details shown in the accompanying illustrations, it being preferable, however, that the vehicle be of a predetermined length to best carry out the operation, as will be hereinafter more fully disclosed. Arranged at the forward extremity of thevehicle is the boring or drilling mechanism comprising a vertically disposed toothed lifting bar or rack 6, operable by means ofa hand wheel 7 located adjacent to the drivers seat 8 and the steering column 9, said wheel being carried by the shaft 10 which has at its outer end the pinion 11 meshing with the lifting bar 6.

Referring particularly to Fig. 3 of the drawings it will be noted that the lower extremity of the bar 6 is looselyl connected to the upper extremity of a bit or auger or other suitable drilling tool 12, the connection permitting free rotation of said auger during movement of the same by said lifting bar. The auger is driven by means of the shaft 3 which is geared with the driving shaft 3 having a beveled pinion 13 at its extremity intermeshing with a similar `pinion 14: on a vertical `shaft 15 supported `has loose connection with the headed extremity of the lifting lever 23 pivotally mounted at 24 on theframe 17. The opposite end of said lever is connected to a foot lever 25, so that it will be obvious upon depression of the foot lever 25 the clutch element 20 will be raised until it frictionally engages the element 21 operativelyconnected to the auger 12, thereby communicating rotation imparted to the clutch element 20 by the shaft 3 to said auger. The auger is operated to drill ahole the proper depth by means of the hand wheel 7 which lowers or raises the bar 6. In actual use the holes in the ground to be operated upon are bored at predetermined distances apart and any suitable means may be employed by Vwhich to determine the interval between said holes, as hereinafter described.

Upon the rear extremity of the vehicle, and indicated at 26, is located certaincharge firing mechanism which forming no part of the'pre'sent invention will not be described as said mechanism is comprehended by my copending application hereinbefore mentioned.

With the foregoing in mind, the operator l disengages the actuating means for rotating the operating tool and raises said tool clear of the ground. The vehicle is then moved through the instrumentality of its motor to the point where the next hole is to be bored in the earth.

As hereinbefore mentioned I preferably employ in conjunction with this apparatus means for automatically bringing the motor vehicle to a stop at redetermined points so as to enable the drilling of the openings in the round by the auger at regular intervals. uch mechanism preferably consists of a cam wheel 44 mounted upon a shaft 45 j'ournaled in a standard 46 near the forward extremity of the machine, which shaft is driven through the driving chains 47, from the vehicle driven shaft 3 as shown most clearly in Fig. 1 of the drawing. The cam wheel 44 is provided with a grooved periphery as indicated at 48, a portion of said groove, at one side of the Wheel, bein deeply cut out as indicated at 49 in Fig. of the drawings. Secured to the frame of the vehicley adjacent the cam wheel 44 is an operating lever 50 normally held in the groove 48 of the cam wheel by means of a spring 51, the lower end of said lever being connected to the brake rod 52 passing to the brake 53 on the rear driving axle of the vehicle.

At 54, (see Fig. 7 is denoted a projecting lu on the cam wheel 44, and the purpose o? the same will now be described. The size of the cam wheel 44 or the ratio of its connection with the drive shaft of the motor vehicle is such that one revolution of this wheel represents the proper interval between a pair of openings which are made by means of the drilling mechanism. When a hole has been made in the ground by the drilling member 12 the operator of the vehicle moves the operating lever 50 onl its pivot so as to engage the same on the lug 54 of the cam wheel and throwing in his clutch the vehicle will move forwardly causing rotation of the cam wheel by reason of its connection with the vehicle drive shaft. I'Vhen the wheel 44 has substantially rotated a single rotation, the lever moving around the groove 48 reaches the deep portion of the groove 49 and under actuation of the spring 51 applies the brake to the vehicle through the operative connection 52 and brings the vehicle to a stop automatically so that the hole drilled as just mentioned will be properlylocated at a predetermined distance from the hole last bored.
